Central location 71 includes processor 75, and processor 75 is connected with terminal 73.

After one group of coating member 101 to 109 is laid and is connected with each other on ground, processor 75 just with coating member 101 to One of 109 processing unit 27 is connected and powered up.When starting shooting, restarting or resetting, processor 75 performs configuration operation.

Figure 10 flow chart can be performed to implement by processor 75 and processing unit 27.In operation 201, processor 75 Output end by central location 71 is that terminal 73 herein sends configuration signal, i.e., " ping ".

In operation 202, configuration signal is received by the first coating member being connected with terminal 73, is portion in the case of Fig. 9 Part 101 is received.The processing unit 27 of part 101 receives signal by the western terminal 19 of one of terminal i.e. herein.Processing unit 27 Identify configuration signal and receive the source terminal of signal, be herein western terminal 19.

The unique positioning for the first component that configuration signal is connected containing central location 71 is identified, and first component herein is Coating member 101.The mark is the coordinate of a pair of (x, y) types here, positioned at the corresponding plane in ground, is defined as origin (0,0).As described below, defining the origin can be with the Information Communication in definition component group 101 to 109 and central location 71.This The positioning mark at place is both the location information of identification information and part 101 relative to parts group of part 101.

In operation 203, configuration information is construed to specify coating member 101 to be parts group by the processing unit 27 of part 101 First component.Processing unit 27 stores the positioning mark (0,0) of coating member 101 in its memory.

Operation 204 can operation 203 perform before, among, perform afterwards.In operation 204, processing unit 27 will be configured The source of signal is construed to referred to as source terminal, western terminal 19 herein.For example, processing unit 27 stores source in its memory The mark of son or input terminal.The mark is " west " here.By determine this orientation can with definition component group 101 to 109 and central location 71 in Information Communication.Western terminal 19 is in being defined as input.

As modification, the configuration signal that central location 71 is launched can be blank, that is to say, that not comprising any positioning letter Breath.In this case, each processing unit 27 is arranged for that in response to receiving empty configuration signal origin will be defined The positioning mark of (0,0) is assigned to the coating member belonging to it.

In operation 205, the processing unit 27 of first component (being herein 101) launches multiple amended configuration signals.This Each in a little amended configuration signals are sent to the other three terminal 15,17, one of 21, and then this other three head is just It is changed into output end.Amended configuration signal includes the positioning mark of transmitting coating member 101, receives coating member herein 102nd, 104 positioning mark, the mark of source terminal, are herein " west " terminal for part 102, are for part 104 " north " terminal.The processing unit 27 of part 101 is according to the mark of transmitting coating member 101 and the terminal of transmission signal come true respectively Determine the mark of part 102,104.For example, the east 17 of part 101 to be transmitted mark corresponding to part 101 Dong-west to Coordinate (x) increases by 1, i.e. (1,0).Similarly, north-south of the mark to be transmitted of the south 21 of part 101 corresponding to part 101 Subtract 1 to coordinate (y), i.e. (0, -1).The identification information to be transmitted iteratively is selected by processing unit 27 herein.

In operation 206, each amended configuration signal is received by each coating member 102,104 for being referred to as receiver, Coating member 102,104 is connected with three lead-out terminals 15,17, one of 21 of emission element 101.Each part 102, 104 processing unit 27 receives signal by one of terminal, here by the western terminal 19 and the North of part 104 of part 102 Son 15 is received.Each processing unit 27 identifies amended configuration information and receives the terminal of signal.Processing unit 27 The mark of source terminal is stored in memory, part 102, part 104 are western terminal 19, the North 15 respectively herein.The terminal in It is defined as input terminal.

In operation 207, each processing unit 27 explains amended configuration signal.Each processing unit 27 is to its memory herein The positioning of the middle coating member 102,104 being stored in respectively belonging to it identifies (1,0), (0, -1) and received from emission element 101 Signal included in source coating member 101 positioning mark (0,0).Processing unit 27 is calculated according to other location informations The location information of part.Use iterative calculation.

Next, receiving part 102,104 is not defined as input each via it, is defined as other the three of output end Each transmission signal in individual terminal.The operation is similar to operation 205, and receiving part 102,104 is current oneself to become hair Part is penetrated, amended configuration signal is launched to juxtaposed other parts 103,105,107.For example, the processing of coating member 102 Unit 27 is identified by the positioning of comparing unit 101 and 102 and determined：Part 101 and 102 is arranged along direction corresponding with reference axis x In a row.In fact, the x coordinate between coating member 101 and 102 is added.Then the processing unit 27 of coating member 102 can (or reduction) positioning mark (1,0) of oneself is to calculate the positioning mark transmitted to each lead-out terminal to increase in some way Know, herein for：Transmitted (2,0) to coating member 103 by the east 17；Transmitted by south 21 to coating member 105 (1, -1).Configuration signal is progressively transmitted like this, and constantly each part being connected with each other in parts group is configured.

Once positioning mark and " input " terminal set and be stored in the memory of processing unit 27, processing unit 27 will be neglected Signal is slightly configured, only to define only one " input " terminal.For example, for the situation of part 105, the processing list of the part Member 27 will only be handled from part 102 or only handled from 104 signals received.This feature is reversible, and can be ordered by resetting Order is cancelled.For example, the specialized signal that central location 71 is launched can remove the signal stored in the memory of processing unit 27.

As modification, configuration signal can limit only to transmit to some lead-out terminals, so that restricted information is exchanged.

According to the modification of configuration process, the triggering state of the pressure sensor 23 of each coating member 101 to 109 is reconstructed simultaneously It is set to reference state.In the calibration steps, if some pressure sensors 23 are detected as state of activation and (detect pressure Power), then processor 75 can ignore the related status information of these sensors 23 in the process of running in the future.On part nobody and Only daily furniture when use this calibrating mode.So pressure sensor 23 detects pressure, the pressure for example produced by furniture During power, it can subsequently eliminate in calculating process, can at least ignore these pressure.In this way, the presence of furniture will not Interferometry, also ensures that the authenticity of alarm.
